[libvirt] [PATCH] Add an example config file for virtlockd



From: "Daniel P. Berrange" <berrange redhat com>

The virtlockd daemon supports an /etc/libvirt/virtlockd.conf
config file, but we never installed a default config, nor
created any augeas scripts. This change addresses that omission.

+# Logging controls
+#
+
+# Logging level: 4 errors, 3 warnings, 2 information, 1 debug
+# basically 1 will log everything possible
+#log_level = 3
+
+# Logging filters:
+# A filter allows to select a different logging level for a given category
+# of logs
+# The format for a filter is one of:
+#    x:name
+#    x:+name
+#      where name is a string which is matched against source file name,
+#      e.g., "remote", "qemu", or "util/json", the optional "+" prefix
+#      tells libvirt to log stack trace for each message matching name,
+#      and x is the minimal level where matching messages should be logged:
+#    1: DEBUG
+#    2: INFO
+#    3: WARNING
+#    4: ERROR
+#
+# Multiple filter can be defined in a single @filters, they just need to be
+# separated by spaces.
+#
+# e.g. to only get warning or errors from the remote layer and only errors
+# from the event layer:
+#log_filters="3:remote 4:event"
+
+# Logging outputs:
+# An output is one of the places to save logging information
+# The format for an output can be:
+#    x:stderr
+#      output goes to stderr
+#    x:syslog:name
+#      use syslog for the output and use the given name as the ident
+#    x:file:file_path
+#      output to a file, with the given filepath
+# In all case the x prefix is the minimal level, acting as a filter
+#    1: DEBUG
+#    2: INFO
+#    3: WARNING
+#    4: ERROR
+#
+# Multiple output can be defined, they just need to be separated by spaces.
+# e.g. to log all warnings and errors to syslog under the virtlockd ident:
+#log_outputs="3:syslog:virtlockd"
+#
+
+# Log debug buffer size: default 64
+# The daemon keeps an internal debug log buffer which will be dumped in case
+# of crash or upon receiving a SIGUSR2 signal. This setting allows to override
+# the default buffer size in kilobytes.
+# If value is 0 or less the debug log buffer is deactivated
+#log_buffer_size = 64
